TI Unveils Zero-Crossover, Rail-to-Rail Amplifier for High-Performance, Single-Supply Applications

July 27, 2006

	

    DALLAS, July 27 /Xinhua-PRNewswire/ -- Texas
Instruments Incorporated (TI) (NYSE: TXN) today introduced
a precision operational amplifier that utilizes an
innovative zero-crossover, single-input stage architecture
to achieve glitchless rail-to-rail performance. Featuring
ultra-low distortion of 0.0006% THD+N, low noise of
4.5nV/rtHz and gain bandwidth of 50MHz, the OPA365 is ideal
for a wide variety of single-supply applications found in
portable instrumentation, data acquisition, test and
measurement, audio and portable medical systems. (See
http://www.ti.com/sc06130 .)

    "The OPA365 leverages TI's expertise in analog
signal conditioning to solve the common design challenge of
finding an op amp that does not limit the capability of the
data converter," said Art George, senior vice
president of TI's high-performance analog business.
"The OPA365's zero-crossover topology, combined with
superior noise and speed performance, solves this design
challenge unlike any other amplifier on the market and
reinforces TI's position as the leading supplier of
high-performance amplifiers."

    The unique single-stage input topology enables
rail-to-rail input without the crossover associated with
traditional complementary input stages. This design reduces
distortion and delivers outstanding common-mode rejection
ratio (CMRR) of 100dB minimum and 120dB typical over the
entire input range (100mV beyond the supply rails), making
it ideal for driving analog-to-digital converters without
degradation of differential linearity. Other features
include fast settling time of 300ns to 0.01%, low offset
voltage of 200uV maximum and single-supply operation from
2.2V to 5.5V. 

    TI provides customers with a state-of-the-art signal
chain solution for precision applications:
analog-to-digital converters such as ADS8327, ADS8361,
ADS7886; digital-to-analog converters such as DAC8811,
DAC8830; and precision voltage references such as REF32xx. 
The OPA365 is also optimized to work with TI's
high-performance TMS320(TM) DSP platforms.

    Availability and Packaging

    The OPA365 is available now from TI and its authorized
distributors in a SOT23-5 package. The device is priced at
$0.95 in 1,000 piece quantities (suggested resale pricing).
An SO-8 package will be available in 3Q 2006. 

    A dual version, OPA2365, will be available in DFN-8 and
SO-8 packages in 3Q 2006. All devices are specified for
operation from -40C to +125C.
